How to disable Google One Tap sign-up prompts?

I disabled this 'feature' a while ago when I saw it on Twitter and forgot about it. However, recently I noticed that Twitter has been able to bypass the setting and was showing me my email under the Google option in the login provider list. I couldn't find any way to disable it.

It uses an iframe scoped to Google and I'm pretty sure that Twitter can't access my Google account data unless I select the login option but still, feels really creepy.

Seems like an issue from 3-4 years ago judging from the date the SuperUser question was posted: Is there some reason this is particularly relevant today I’ve missed?

Features like this really creep me out - even if they are appropriately scoped or contained in a clever i frame. Thankfully, on Firefox you can put everything that legitimately needs your google account information into a container and have the information remain inaccessible outside the container.

It’s one of the most user friendly and privacy centric features available in a browser.

I’ve never seen these. I don’t know if it’s because I disable third party cookies, because I never log into Google using my main browser profile, or because of my ad blocker.
